Ranking the 10 best defenders in the world: Top 10 centre-backs this season 

#3 Kalidou Koulibaly (Napoli)

SSC Napoli's Kalidou Koulibaly

Kalidou Koulibaly is the hottest property in Europe at the moment and the biggest teams in Europe are fighting for his signature. The 27-year old is one of the most complete centre-backs there is in Europe. He has made 38 appearances for Carlo Ancelloti's Napoli and is a crucial member of his squad.

He is exceptional on the ball and can drive the ball forward, has bags of pace and wins almost every challenge he commits to. The Senegalese centre-back is a brilliant passer of the ball and completes 88% of his attempted passes, averaging 73 passes per game. He stands 195cm above the ground and his physicality is unmatched.

Koulibaly wins 2.2 aerial duels per game, wins 1.7 tackles per game, and completes 1.4 interceptions per game. The centre-back has played against the best attackers in Europe this season and came out on top every time. Potential suitors are willing to pay north of £100 million which explains the confidence they have in his ability.
